At Caernarfon Castle in Wales, Prince Charles was invested as the Prince of Wales. This title, given to him on July 1, 1969, made him the next heir to the British throne after his mother Queen Elizabeth II.

On December 11, 1936, Edward VIII, king of Great Britain and Ireland, broadcasts his decision to renounce his throne. Because he insisted on marrying the twice-divorced American Wallis Simpson, Edward had no choice but to abdicate.
